Question one - no but you are right InControl is the solution.
Question two - better yet we can use SNMP or SSH CLI to pull the usage data out of the unit.
Question three - there is, check this out.
Question four - that I believe is the reset button you are looking for in question three?
Question five - yes usage will be available on InControl.

On my device if I use any one of several SSH clients, typing “get bandwidth daily” is as far as I can get as I am unable to enter a date and the device will just freeze at that point. An hour later it is still frozen.

Any bandwidth command gives the same result. I opened a case about the issue a week or so ago. SNMP gives multiple layers of giberish.

The symbol for the reset button looked like the symbol for a pot. Not wanting to mess with things, I left it alone, but your right it is a reset!

I was also sent a new firmware file for the device but unfortunately the device will not accept it in spite of several reboots and resets. Using the older version of firmware that is also installed in the device give the same sort of results with several features missing.

It’s a little cumbersome but for now I have been doing a copy, paste, print to save the data.

Just in case, I tried using my wife’s computer and changing the default browser on my computer from Firefox to IE, Chrome, and Safari with the same results.

I just looked and it seems that there are three case files open. 735194, 735720, and 735711. Probably my fault as I contacted Pepwave and then the 3gstore.
